SHEETTIVIETAL ROOFING.

SPECIFICATION forming part of Letters Patent No. 492,513, dated February28, 1893. Application filed April '77, 1890. Serial No. 346,890. (Nomodel.)

i .To all whom it may concern:

Be it known that I, ALVIN C. KANNEBERG, a citizen of the United States,and a resident of Canton, county of Stark, State of Ohio, have inventeda new and useful Improvement in Sheet-Metal Booting, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, making part of this specification.

My invention relates to improvements in sheet metal rooting and consistsin certain features of construction and combination of parts as will behereinafter described and pointed out in the claims.

Figure l. of the accompanying drawings is a View in perspective showingportions of two sheets having their edges turned or flanged upwardlytogether with the anchor. Fig. 2. is a transverse section through thesheets and the central portion of the anchor showing the wide flangehemmed over the top of the anchor and the tongue of the anchor over thenarrow flange. Fig. 3. is a similar View showing the wide iiange and theanchor bent together. Fig. 4. is a similar View showing the seamcompleted. Fig. 5. is a perspective of a portion of a roof showing thesheets of metal in position and seamed together. Figs. 6 and 7 aredetailed perspective views.

Similar letters of reference indicate corresponding parts in all of thefigures of the drawings.

A, represents the sheets of which the roof is formed, which may be ofany desired length or width having their edges flanged as shown, usuallythe one side turned to form the narrow [lange a about one inch high, theother side turned to form the wide flange o about one and a half incheshigh, the top portion turned over to form the hem e.

The anchor C is formed substantially as shown by the drawings, having ahorizontal portion to be nailed to the sheeting boards, and averticalvportion to be folded into the seam. The latter portion havingprovided therein a tongue c integral therewith, the free end of which isdirected downward as shown in Fig. 1.

In construction the metal sheets A are placed upon the sheeting board asshown in Fig. 5, the anchors O placed in position as shown in Figs. 6and 7, the tongue c over the flange a, the horizontal portion nailed tothe sheeting, the second sheet is then placed against the anchor asshown in Fig. 2, and the top of the flange turned over the top of theanchor forming the hem c, as shown in Figs. l and 2, after which theseam is further bent as shown in Fig. 3, after which it is bent down andthe seam completed as shown in Fig. 4, the tongue c indented into theflange a and the latter indented intothe perforation f formed in theanchor by the cutting out of the free end of the tongue, therebyreducing the thickness of the seam.

It will be seen that by the use of anchors formed as hereinbeforedescribed the labor of bending the tongue ora portion of the anchor overthe flange d is avoided, the anchor being used in the construction ofthe roof in the original form in which it leaves the factory.

Having thus fully described the nature and object of my invention, whatI claim as new, and desire to secure by Letters Patent, is-

l. The combination of the sheets A having flanges a and ZJ, thelatterprovided with the hem c, the anchor O, having a tongue c formedfrom and integral at its top portion with said anchor, the downwardlyprojected free end to embrace the flange a, substantially as describedand for the purpose set forth.

2. The combination of the sheets A, having flanges o. and h, the anchorC having a tongue formed therefrom and integral therewith at its top,and the flange b, and anchor C folded over the flange o, and the tonguec, indented into the flange a, substantially as described and for thepurpose set forth.

In testimony whereof I have hereunto set my hand this 2d day of April,A. D. 1890..

CHAs. R. MILLER, ATLEE POMERENE.
